How I architect full-stack systems
Product Architecture
Define user flows, feature requirements, database schema, and API contracts before development begins.
Frontend Foundation
Next.js App Router with Server Components for performance, responsive Tailwind layouts, and accessible UI components.
Backend & Data
RESTful APIs with NestJS or Express, PostgreSQL/MongoDB schemas, auth middleware, and payment webhook handling.
Integration & Polish
Connect frontend to API, add real-time features, optimize Core Web Vitals, and implement error boundaries.

Planfluence
Meetings into Momentum — AI Meeting Intelligence to Jira Backlog & Slack Recaps
Problem
Engineering discussions frequently end with action items and architectural commitments buried in unreviewed recordings or chat threads. Translating spoken consensus into Jira tickets with acceptance criteria wastes hours of developer and manager time.
Solution
Architected a 4-step pipeline: (1) Capture calls via Google Meet Chrome extension without intrusive bots; (2) Transcribe and extract decisions using Whisper and LLMs; (3) Review, approve, and publish tickets directly to Jira Cloud/Data Center and Trello backlogs; (4) Broadcast structured recaps to dedicated project Slack channels.
Architecture
- Chrome Extension (Manifest V3) capturing tab audio locally with zero bots joining user meetings
- Next.js 15 App Router web application with streaming AI summaries and interactive decision editor
- High-speed Whisper transcription & structured JSON extraction for action items and acceptance criteria
- Bi-directional Jira Cloud & Trello API integrations with one-click backlog and sprint publishing
- Slack webhook automation broadcasting project-specific meeting recaps with deep links
- Lemon Squeezy merchant-of-record subscription billing engine

GeniSteps
Hardware-Accurate Step Tracking & Vitality Companion — 100% Local-First
Problem
Mainstream pedometers drain device battery, lock essential 24-hour trends and data exports behind $39–$79/yr recurring subscriptions, and harvest sensitive biometric location and movement data to proprietary cloud servers.
Solution
Built a silicon-native motion engine with a 4th-order DSP bandpass filter (0.8–3.5 Hz) tuned to human gait biomechanics. Features silent lock-screen updates via >95% IPC throttling, natural stride pacing (~320ms), and 100% data sovereignty in on-device SQLite WAL mode.
Architecture
- Silicon coprocessor integration: Apple CoreMotion (CMMotionActivityManager) & Android Sensor Hub
- 4th-Order DSP digital signal processing filter (0.8–3.5 Hz) isolating true strides from vehicle vibration
- Silent lock-screen live activity widgets with >95% IPC throttling for battery preservation
- Local-first SQLite database running in WAL mode with instant 1-tap CSV and JSON spreadsheet export
- Behavioral habit psychology engine: automated bankable streak freezes and rest-day scheduling
- Standardized machine-readable /llms.txt factsheet for generative engine and AI model evaluation

DispatchLink
B2B Freight Marketplace Connecting Carriers & Dispatchers
Problem
Freight dispatching is plagued by manual phone calls, untracked load confirmations, fragmented broker commissions, and slow escrow reconciliation.
Solution
Architected a unified real-time portal where carriers claim loads with automated geospatial radius search, live driver telemetry, and automated multi-tenant wallet payouts.
Architecture
- Next.js 15 App Router with Server Components for low-latency freight searches
- MongoDB 2dsphere indexes for polygon and radius origin-to-destination matching
- MapLibre vector maps rendering live driver routes and telemetry coordinates
- LemonSqueezy merchant-of-record integration for multi-party escrow billing

Kookabe AI Suite
Enterprise WhatsApp RAG Chatbot & Automated AI Voice Mail
Problem
Companies received hundreds of repetitive WhatsApp voice notes, PDFs, and product inquiries daily, resulting in 4-8 hour response delays and missed sales leads.
Solution
Built a hybrid RAG system with pgvector and Claude 3.7 that parses customer inquiries, searches internal PDF documentation, and generates accurate answers with human-handoff triggers.
Architecture
- WhatsApp Business API webhooks ingesting incoming text, voice notes, and document files
- Hybrid RAG combining pgvector dense embeddings with BM25 keyword reranking
- FastAPI backend handling asynchronous LLM streaming and conversation state
- Automated audio transcription pipeline extracting lead data directly into CRM webhooks

FAQ
Frequently asked questions
Do you build entire SaaS products from scratch?
Yes. I've founded The Geni Solutions and shipped production platforms like Planfluence (AI meeting-to-backlog SaaS) and GeniSteps (local-first mobile companion) from database design to deployment. I own the complete vertical — frontend, backend, auth, payments, DevOps.
What's your frontend tech stack?
Next.js 15/16 with App Router and Server Components, React 19, TypeScript, and Tailwind CSS. I build responsive, accessible interfaces with strong Core Web Vitals performance.
Can you work on an existing codebase?
Absolutely. I audit existing code, identify performance bottlenecks, refactor architecture where needed, and add new features without breaking existing functionality.
Do you handle payments and auth?
Yes — I integrate LemonSqueezy and Stripe for payment processing, webhooks, and multi-party escrow. For auth, I implement JWT, OAuth, and role-based access control.
Need a complete SaaS platform built?
From UI to API to deployment — I own the entire stack and ship production products.
